How do I include variables in my VagrantFile?
提问by MechaStorm
Can anyone guide me to how do I include variables in my VagrantFile? I am trying to inject configs into the Vagrantfile from an external file so that I can distribute the config to my colleagues without having them to hardcode configs directly on the Vagrantfile.
谁能指导我如何在 VagrantFile 中包含变量？我正在尝试从外部文件将配置注入 Vagrantfile，以便我可以将配置分发给我的同事，而无需他们直接在 Vagrantfile 上硬编码配置。
I had thought that since it was Ruby based I could just include a Ruby file but I get an error Message: unintialized constant MyVars
我原以为因为它是基于 Ruby 的，所以我可以只包含一个 Ruby 文件，但我收到一条错误消息：未初始化的常量 MyVars
My VagrantFile simplified
我的 VagrantFile 简化了
# -*- mode: ruby -*-
# vi: set ft=ruby :
require 'vagrant.rb'
include MyVars
Vagrant.configure("2") do |config|
# Web
config.vm.define :joe do |joe|
joe.vm.box = "precise64_4.2.12"
joe.vm.hostname = WEBVMNAME
joe.vm.network :private_network, ip: "192.168.140.141"
# Port Forwarding
joe.vm.network :forwarded_port, guest: 22, host: 2201
joe.vm.network :forwarded_port, guest: 80, host: 8080
# Bootstrap Bash Script
joe.vm.provision :shell, :path => "bootstrap.sh"
end
end
And vagrant.rb contains
而 vagrant.rb 包含
module MyVars
WEBVMNAME = "rex"
end
Do note that I am also a newbie at Ruby so I am not sure as well if its just the syntax I got wrong?
请注意，我也是 Ruby 的新手，所以我也不确定它是否只是我弄错的语法？
